Solar in Cape Town

Cape Town has a Mediterranean climate with long, sunny, dry summers and wetter, cloudier winters, so solar output peaks in the warm months and dips in winter. The City of Cape Town supplies most of the metro and requires small-scale embedded generation to be registered and approved, with only approved inverters and installers accepted for grid-tied and hybrid systems. The south-easter wind, salt air on the Atlantic Seaboard and corrosion near the coast demand engineered mounting and marine-grade fittings. Roofs include tile, IBR, slate and flat concrete in apartment blocks, and heritage or body-corporate rules affect some properties. Hybrid backup, solar geysers and commercial rooftops are very popular.

Typical off-grid solar systems requests in the area come from:

  • Family homes: rarely fully off-grid, though some owners go grid-free with large battery banks and a generator
  • Estate homes: occasional off-grid homes where the estate allows it, with ground or roof panels and generous storage
  • Townhouses and flats: seldom suitable for townhouses, though off-grid common-area lighting or gate systems are sometimes installed
  • Shops, offices and schools: remote shops, guest lodges and rural clinics that need steady power where the grid is unreliable
  • Factories and warehouses: mines, remote sheds and pump stations running on dedicated solar, battery and generator systems
  • Farms, smallholdings and lodges: farmhouses, labour housing and lodges far from the grid, often powered with a generator backup

Why get a quote in Cape Town first?

Prices for off-grid solar systems in Cape Town depend on the system size, the equipment, the roof, the wiring run, the paperwork and how soon you need it. A quote based on your details is the quickest way to know what you will pay, and it shows what is included before anything is ordered.

What to include in your request

  • List every appliance and how long it runs each day.
  • Say which is the largest motor to start, such as a pump.
  • Describe the site: roof, open ground, coast or inland.
  • State how many cloudy days of storage you want.
  • Mention if a generator already exists and its size.

The more detail you give, the more accurate your quote will be.

Frequently asked questions

What will it cost in Cape Town?
It depends on the size of the system, the equipment chosen, the roof, the distance from the inverter to the distribution board, the paperwork for your electricity supplier and how soon you need it done. Tick your loads on the form and a solar installer working in Cape Town will quote you.
Will someone come out to look at the property?
Yes, for most jobs. The person quoting needs to see the roof, its direction and shading, the distribution board and where the inverter and batteries will go. Give your suburb on the form and they will arrange a visit.
How much sun is there in Cape Town?
A north-facing array in Cape Town makes about 4.9 kWh per kWp a day averaged over the year. Shade from trees or neighbours, the roof angle and dust change this, so the installer will check your roof.
